Why this matters

The creator of the most popular AI coding assistant hasn't touched code in a month. The tool is building itself.

This is either the most exciting or terrifying milestone in software development — depending on who you ask. Either way, we're watching the job of "software engineer" transform in real-time.

The context

SoftBank's $40B investment makes them OpenAI's largest shareholder at ~11%. To fund this, Masa Son sold his entire Nvidia position — a $5.8B bet that OpenAI will outperform Nvidia long-term.

Stargate is their joint infrastructure venture. The thesis: whoever controls AI compute controls AI.

Two major releases in one day

Tencent dropped both HY-Motion (text-to-3D-animation) and HY-MT1.5 (translation models). The translation models won WMT25 and run on-device with just 1GB memory.

China's open-source AI push continues at full speed.
